W&H has just celebrated 30 years of Assistina 301, a maintenance device released in 1992 which provides care and performs accurate lubrication cycles for the function and long working life of dental handpieces.

The air-driven Assistina 301 plus is designed for straight and contra-angle handpieces, turbines, air motors, and air-driven scalers. During a maintenance cycle, it cleans the spray channels with cleaning fluid, lubricates the gear parts with W&H Service Oil, and finally dries the instruments with compressed air. According to W&H, these steps are completed within “35 seconds” at the touch of a button.

In combination with the W&H thermal washer disinfectors Teon or Teon +, and one of W&H’s steriliser models, Assistina 301 plus ensures high hygienic standards.

Compared to traditional oil spray cans, the automatic oil dispensing system accounts for a cost reduction of 90%, as claimed by W&H. This makes automatic instrument maintenance not only convenient, but also effective in caring for transmission instruments.

Adaptors to fit other manufacturers’ handpieces are yet another convenient feature: straight and contra-angle handpieces with ISO connection do not require adaption at all, and there is a portfolio of adaptors to ensure compatibility with any other certified system.
